The transmission coefficients of electromagnetic(EM) waves due to a superconductor-dielectric superlattice are numerically calculated.Shift operator finite difference time domain(SO-FDTD) method is used in the analysis.By using the SO-FDTD method,the transmission spectrum is obtained and its characteristics are investigated for different thicknesses of superconductor layers and dielectric layers,from which a stop band starting from zero frequency can be apparently observed.The relation between this low-frequency stop band and relative temperature,and also the London penetration depth at a superconductor temperature of zero degree are discussed,separately.The low-frequency stop band properties of superconductor-dielectric superlattice thus are well disclosed.
